Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454458, here are decompositions:

17 + 31454441 = 31454458
107 + 31454351 = 31454458
137 + 31454321 = 31454458
239 + 31454219 = 31454458
257 + 31454201 = 31454458
311 + 31454147 = 31454458
461 + 31453997 = 31454458
467 + 31453991 = 31454458

Showing the first eight; more decompositions exist.
